were found. Colias interior and Argynnis atlantis were at- 

 tracted by a small orchid and other flowers. Among the but- 

 terflies Colias interior, Chrysophanits epixanthe and such 

 moths as Diastictis brunneata and D. sulphnrea were frequent- 

 ly found in the wild cranberry marshes and sphagnum bogs 

 along Cranberry and Doe Lakes. 



(c) Tamarack Szvauips: Extensive tamarack swamps oc- 

 cur as shown on the accompanying map. A variety of small 

 shrubs and plants which sometimes form dense thickets occur 

 in this habitat. Little collecting was done here. 



Sandy Ridges or Old Sand Dunes, (a) Open Mixed Wood- 

 land: In this habitat the jack pine predominates with scat- 

 tering mixed stands of hard maple, white pine, aspen, birch 

 and a little black oak, while spruce and tamarack sometimes 

 occur on the lower portions adjacent to swamp areas. A 

 varied ground cover of blueberry, many allied plants and 

 brake fern usually occur, although in some places reindeer 

 moss and xerophytic grasses form the ground cover. Many 

 sandy ridges at the Point would fall under this habitat, es- 

 pecially those along the mail road from Whiteiish Point Post 

 Ofiice to the schoolhouse and from the Post Office towards 

 Vermillion for about two or three miles. 



Such butterflies as Limenitis arthemis and G rapt a j'-albitni 

 were quite common along the roadside, while Colias interior 

 and Argynnis atlantis were frequently seen. Such Geome- 

 tridse as Dcilinia variolaria, Metrocampa pcrlata, Sciagraphia 

 granitata, Xanthotype crotaria and others were frequently 

 flushed up from the underbrush. Among the microlepidoptera 

 many species of the Tortricidse were beaten from shrubs 

 along the roadside. A number of species of Geometridse were 

 found on the trunks of trees where they had taken refuge for 

 the dav.
